Fig. 34 — Powered Convenience Outlet Wiring

DUTY CYCLE
The unit-powered convenience outlet has a duty cycle limita-

tion. The transformer is intended to provide power on an inter-

mittent basis for service tools, lamps, etc; it is not intended to

provide 15A loading for continuous duty loads (such as electric

heaters for overnight use). Observe a 50% limit on circuit load-

ing above 8A (i.e., limit loads exceeding 8A to 30 minutes of

operation every hour).
MAINTENANCE
Periodically test the GFCI receptacle by pressing the TEST

button on the face of the receptacle. This should cause the in-

ternal circuit of the receptacle to trip and open the receptacle.

Check for proper grounding wires and power line phasing if

the GFCI receptacle does not trip as required. Press the RESET

button to clear the tripped condition.
FUSE ON POWERED TYPE
The factory fuse is a Bussmann Fusetron

T-15, non-renewable

screw-in (Edison base) type plug fuse.
USING UNIT-MOUNTED CONVENIENCE OUTLETS
Units with unit-mounted convenience outlet circuits will often

require that two disconnects be opened to de-energize all pow-

er to the unit. Treat all units as electrically energized until the

convenience outlet power is also checked and de-energization

is confirmed. Observe National Electrical Code Article 210,

Branch Circuits, for use of convenience outlets.

SMOKE DETECTORS

Smoke detectors are available as factory-installed options on

581J models. Smoke detectors may be specified for supply air

only, for return air without or with economizer, or in combina-

tion of supply air and return air. Return air smoke detectors are

arranged for vertical return configurations only. All compo-

nents necessary for operation are factory-provided and mount-

ed. The unit is factory-configured for immediate smoke detec-

tor shutdown operation; additional wiring or modifications to

unit terminal board may be necessary to complete the unit and

smoke detector configuration to meet project requirements.

System

The smoke detector system consists of a four-wire controller and

one or two sensors. Its primary function is to shut down the roof-

top unit in order to prevent smoke from circulating throughout

the building. It is not to be used as a life saving device.

Controller

The controller (see Fig. 35) includes a controller housing, a

printed circuit board, and a clear plastic cover. The controller

can be connected to one or two compatible duct smoke sensors.

The clear plastic cover is secured to the housing with a single

captive screw for easy access to the wiring terminals. The con-

troller has three LEDs (for Power, Trouble and Alarm) and a

manual test/reset button (on the cover face).

Smoke Detector Sensor

The smoke detector sensor (see Fig. 36) includes a plastic

housing, a printed circuit board, a clear plastic cover, a sam-

pling tube inlet and an exhaust tube. The sampling tube (when

used) and exhaust tube are attached during installation. The

sampling tube varies in length depending on the size of the

rooftop unit. The clear plastic cover permits visual inspections

without having to disassemble the sensor. The cover attaches to

the sensor housing using four captive screws and forms an air-

tight chamber around the sensing electronics. Each sensor in-

cludes a harness with an RJ45 terminal for connecting to the

controller. Each sensor has four LEDs (for Power, Trouble,

Alarm and Dirty) and a manual test/reset button (on the left

side of the housing).
